Abstract

Un'apparecchiatura di visualizzazione di immagini tridimensionali con campionato in profondità visualizza un'immagine tridimensionale, senza l'uso di occhiali. L'apparecchiatura comprende un dispositivo di proiezione della luce collimata per proiettare luce collimata, ed un oggetto di osservazione che attraversa sostanzialmente tutte le componenti della luce collimata, senza provocare rifrazione o diffrazione, e che ha scritte in esso informazioni per provocare la riflessione casuale della luce collimata, rappresentativa di un'immagine tridimensionale. L'apparecchiatura comprende inoltre un condensatore convesso di grande diametro per concentrare la luce passata attraverso l'oggetto di osservazione, un filtro spaziale che ostruisce il passaggio della luce solo in un'area comprendente l'asse ottico e le sue vicinanze, per eliminare la componente di flusso diretto della luce introdotta mediante il condensatore convesso di grande diametro, ed una lente per la produzione di immagini, convessa e di grande diametro, per mettere a fuoco la luce passata attraverso il filtro spaziale, per formare un'immagine tridimensionale.A three-dimensional image display equipment with depth sampling displays a three-dimensional image, without the use of glasses. The apparatus comprises a collimated light projection device for projecting collimated light, and an observation object which substantially passes through all the components of the collimated light, without causing refraction or diffraction, and which has information written therein to cause the random reflection of the collimated light, representative of a three-dimensional image. The apparatus also comprises a large diameter convex condenser for concentrating the light passed through the observation object, a spatial filter that obstructs the passage of light only in an area comprising the optical axis and its vicinity, to eliminate the direct flow component of the light introduced by the convex capacitor of large diameter, and a lens for the production of images, convex and large diameter, to focus the light passed through the spatial filter, to form a three-dimensional image.
